About Acres

An acre is a traditional unit of land area used primarily in the United States, United Kingdom, and countries with British heritage. One acre equals 43,560 ft² or about 4,047 m². Historically based on the area a yoke of oxen could plow in one day, it remains the standard for measuring agricultural land, residential plots, and rural properties. A football field (without end zones) is roughly 1.32 acres, and most suburban house lots range from 0.25 to 1 acre.

About Dunam

A dunam (also dönüm or donum) is a unit of land area equal to exactly 1,000 m², used across Turkey, Israel, Palestine, Jordan, Lebanon, Iraq, and former Ottoman Empire territories. One dunam equals one stremma and one decare. The modern metric dunam of 1,000 m² was standardised during the British Mandate period; older Ottoman dunams varied by region (approximately 919-1,600 m²). It remains the primary land measurement unit for agricultural and property records throughout the Middle East, with properties routinely listed in dunams in Israeli and Palestinian real estate.
